SELF-LUBRICATING SHELL-ROLLER.

SPECIFICATION forming part of Letters Patent No. 597,968, dated January25, 1898.

Application filed September 25,1897. Serial No. 658,062. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM BINGHAM FARRAR, MONT ROYAL FARRAE, andNEILL ALEXANDER CLARK, citizens of the United States, residing atGreensborough, in the county of Guilford and State of North Carolina,have invented new and useful Improvements in Self-LubricatingShell-Rollers, of which the following is a specification.

This. invention relates to that type of shellrollers employed incotton-factories, woolenmills, and other places wherein roller shells orsleeves of metal rotate upon metal arbors or shafts mounted in racks orsupports and held :5 down in their bearings by weights. These rollersrequire to be lubricated or oiled more or less frequently, andordinarily this is inconvenient and troublesome to accomplish andinvolves the loss of time, in that the arbors or shafts require to beremoved from their bearings, the roller shells or sleeves slippedtherefrom, the parts wiped and lubricated or oiled, and then reassembledin operative position.

a The object of our present invention is to provide a new and improvedself-lubricating shell-roller of such construction that it is nevernecessary to remove the arbor or shaft or the roller shell or sleeve forlubricating or o oiling'purposes.

- To accomplish this object, the invention consists, essentially, in thecombination of a roller shell or sleeve, an arbor or shaft having alongitudinal bore extending about half its length and a transversepassage leading from the bore, and an agitator-pin located in thetransverse passage-way and having a shank extending through the arbor orshaft to make contact with the internal surface of the 0 roller shell orsleeve, so that when the arbor or shaft is held stationary and theroller shell or sleeve is rotated the shank will be acted upon in suchmanner as to more or less rapidly jar or vibrate the shank and pin forthe purpose of accurately feeding from the inte rior of the. arbor orshaft exactly the quantity of lubricant or oil required to preserve theparts in the proper condition for smooth running, while leakage of thelubricant or oil or the supply of a superfluous quantity of the same tothe contacting surfaces of the roller shell or sleeve and the arbor orshaft is effectually prevented.

The invention is illustrated by the accompanying drawings, in which--Figure 1 is a longitudinal central sectional view of the new andimproved shell-roller. Fig. 2 is a transverse sectional view taken onthe line 2 2, Fig. 1. Fig. 3 is a transverse sectional view taken on theline 3 3, Fig. 1, looking at the perforated part of the tubular socketin which the agitator-pin is located. Fig. 4 is a detail end elevationshowing the manner in which the arbor or shaft is mounted in a rack orsupport andis prevented from 65 rotating, and Fig. 5 is a detail endelevation showing a modification of the means for preventing the arboror shaft rotating,

In order to enable those skilled in the art to make and use ourinvention, we will now describe the same in detail, reference being madeto the drawings, wherein-- The numeral 4 indicates an arbor or shaftdrilled or otherwise provided with a longitudinal bore 5, leading fromone end thereof to aboutthe middle ofits length, so that while about onehalf of the length of the arbor or shaft is tubular the other half maybe solid, as shown in Fig. 1. The arbor or shaft is also drilled orotherwise constructed about the middle ,of its length with a transverseorifice in which is inserted a tubular metal socketfi, having one endopen, as at 7, and the other end provided with a diaphragm containing asmall opening 8. The side of the tube presented to the main body of thebore 5 is constructed with a plurality of small perforations 9, designedto permit the passage of lubricant or oil contained in the bore 5 intothe tubular socket, from which it may flow in minute particles throughthebpenlng 8 into a longitudinal oil-distributing groove t, formed in'the-under side of the arbor or shaft. The tubular portion of the arboror shaft is provided in its outer end with a plug 12, which serves toclose the bore, and near this plug the arbor or shaft is constructedwith atransverse supply-orifice 13, closed by a removable andreplaceable stopper 14 for supplying the lubricant or oil to the bore 5.100

This bore may contain a filling of absorbent material 15-such as rawcotton, thread, or sponge-whicl1 will be thoroughly saturated with thelubricant or oil. If this absorbent filling is employed, it is advisableto provide the bore 5, at a point in proximity to the perforated part 9of the tubular socket 6, with a cross-pin or a wire-gauze disk 16 toprevent the perforation being closed and also to prevent the absorbentfilling from interfering with the motion of the agitating-pin should thetubular socket 6 be dispensed with.

The arbor or shaft is in practice mounted in a rack or support and isheld against rotating or turning while the roller shell or sleeverotates thereupon. The arbor or shaft may be held against rotating orturning through the medium of two inclined pins 17, Fig. 4, which bearagainst the vertical walls of the bearing provided in the rack orsupport to receive the arbor or shaft or through the medium of a stirrup17, havinga weight 17" at its lower end and constructed with a flattenedsurface resting against a flattened surface 17, formed on the upper sideof one end of the arbor or shaft, as shown in Fig. 5.

The bore 5 constitutes an oil-reservoir, which is supplied with theproper quantity of lubricant or oil through the supply-orifice 13,which, as before stated, is closed by the removable and replaceablestopper 14.

The tubular socket 6 contains a loose agitating device composed of a pin18, having a shank 19, which passes freely through the orifice 8 in oneend of the socket. The extremity of the shank 19 makes contact with theinternal surface of the roller shell or sleeve 10, and when the latterrotates upon the arbor or shaft the transversely-movable pin and theshank will be more or less rapidly jarred or vibrated, and thus causethe lubricant or oil to flow in minute particles through the orifice 8into the longitudinal oil-distributing groove 4, by which means thecorrect quantity of lubricant will be supplied to the arbor or shaft andthe roller shell or sleeve for maintaining these parts in the bestcondition for smooth running.

The shank 19 is screw-threaded and screwed into the pin 18, so that theshank is lengthwise adjustable to compensate for wear at the end whichcontacts with the internal surface of the roller shell or sleeve. y

The lubricant or oil will pass from the bore 5, which constitutes theoil-reservoir, through the perforations 9 into the tubular socket 6, andthe rapid vibrations of the agitating-pin, which are of course limitedin extent, serve to accurately feed the proper quantity of lubricant oroil to the oil-distributing groove 4*, the construction being such thatthe feeding of a superfluous quantity of lubricant or oil is efiectuallyprevented, while the parts are properly lubricated without any attentionfrom an attendant other than supplying the oil-reservoir with thelubricating substance.

The present invention provides novel, simple, eflicient, and economicalmeans for automatically lubricating shell rollers and entirely avoidsthe inconvenience, trouble, and loss of time incident to removing thearbors or shafts from their bearings, detaching the roller shells orsleeves, wiping and oiling the parts, and then reassembling them eachtime lubrication may be considered necessary.
